Abstract

A method for communication includes establishing communications over a wireless local area network (WLAN) between one or more access points (22, 24, 26, 28) and a group of mobile stations (34, 36, 38, 40) in a first basic service set (BSS) using a first BSS identifier (BSSID). Upon detecting initiation of a communication session of a predetermined type involving a mobile station in the group, the mobile station is assigned to a second BSS having a second BSSID. The communication session continues by transmitting and receiving signals between an access point in the WLAN and the assigned mobile station using the second BSSID.
